APPARATUS AND METHOD FOR TRANSMITTING PUNCTURED OR REPEATED DATA

摘要

Data communications apparatus which operates to communicate data frames (8), said apparatus comprising means (12) for converting the data frames (8) into data blocks (14) for transmission, which data blocks are of a size which is different to that of the data frames. The means (12) for converting the data frames includes means (PR) for puncturing or repeating bits or symbols at positions within the data frame determined in accordance with a selection strategy, wherein the selection strategy is arranged to provide an equal distribution of the positions throughout the data frame. The selection strategy is effected according to one embodiment with a digital differential analyser type algorithm.
